Ignition switch for 25hp Merc?

[nola mike]

Key broke off in the ignition switch. Tried replacing with a Sierra, but the body was too wide and the throttle box wouldn't close (realized after wiring everything in. boo). Trying to find the correct switch now, but can't find the part. S/N is 0T777364. Would love to get this part by the weekend. Thanks!

No, it looks like this one; Sierra MP41070-2 Switch, Ignition

I can't seem to find the correct switch in the parts diagram [h=1][/h]
